What is the difference between a controlled bottle and a molded bottle?

1. Appearance: The control bottle is more transparent than the molded bottle. The bottom of the control bottle should be thin, and the bottom of the molded bottle should be thick and not uniform. Some of them are uneven. The error of the outer diameter of the tube should be smaller for the control bottle!
2. Material: The control bottle is generally low borosilicate in China, but medium borosilicate can also be made, and the molded bottle is sodium calcium, because the material is inferior to the control bottle in drug resistance and acidity.
3. Features: Control bottles can be used for freeze-drying, but not molded bottles!
4. Price: There are also controlled bottles that are more expensive than molded bottles!
5. Production: The production of controlled bottles is more flexible. Molding bottles requires opening glass molds, and the production cycle is relatively long.
Sixth, transportation: the weight of the control bottle is relatively light, and the weight of the molded bottle is relatively heavy. Lightweight transportation costs will be greatly reduced.
